Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example being heating iron ore in a furnace at a high temperature of 800 to 1,200 °C (1,470 to 2,190 °F) in the presence of the reducing gas syngas ...

Sep 13, 2024 · Sponge iron, also known as direct reduced iron (DRI), is a highly versatile and essential material in the steel industry. It is characterized by its porous structure, which resembles a sponge, hence the name.

Pig iron is primarily used in the production of cast iron and wrought iron, while sponge iron serves as a raw material for steelmaking. Understanding the differences between these two forms of iron is crucial for selecting the appropriate material for specific industrial applications.

This article delves into the essence of sponge iron, its production process, applications, benefits, and the impact it has on the global steel market. Sponge iron, also known as direct reduced iron (DRI), is a product of the direct reduction of iron ore.

DRI, also known as sponge iron, is the product of reducing iron oxide in the form of iron ore and steel plant wastes into metallic iron, below the melting point of iron and typically in the range of 800–1200°C.

Jan 7, 2024 · Sponge iron is a metallic product made through the direct reduction of iron ore in the solid state. It is also known as naturally reduced iron (DRI). The process of making sponge iron aims to expel oxygen from the iron ore and increase its quality.

Mar 16, 2013 · Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes. The reducing agents are carbon monoxide (CO) and hydrogen (H2), coming from reformed natural gas, syngas or coal.

Mar 11, 2024 · Direct-reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore by a reducing gas produced from natural gas or coal.

Direct reduced iron (DRI), also called sponge iron due to its porous nature, is produced in reactors that directly reduce (remove) the oxygen from the iron oxides in iron ore. Unlike the chemical reactions that happen in the blast furnace, the DRI process …

Mar 17, 2025 · Sponge iron, or direct reduced iron, plays a pivotal role in the steel industry by aiding in the reduction of iron oxide through reactions with carbon. As a major contributor, India produces 20% of the world’s sponge iron with over 200 plants.
